Comet 13P/Olbers Returns to Inner Solar System: Last Seen in Year 1956

Comet 13P/Olbers Returns to Inner Solar System: Last Seen in Year 1956

  

Comet 13P/Olbers is returning to the inner Solar System after 68 years. This periodic, Halley-type comet will reach its next perihelion or closest approach to the Sun on June 30, 2024. It can be viewed with binoculars in the night sky of planet Earth's northern hemisphere. 

This sharp telescopic image of 13P is composed of stacked exposures made on the night of June 25. It easily reveals shifting details in the bright comet's torn and tattered ion tail buffeted by the wind from an active Sun, along with a broad, fanned-out dust tail and slightly greenish coma. The frame spans over two degrees across a background of faint stars toward the constellation Lynx.

13P/Olbers fits the classical definition of a Halley-type comet with a period between 20 and 200 years. This comet was last seen in 1956. German astronomer Heinrich Wilhelm Matthias Olbers discovered this comet on March 6, 1815.

Galaxy Messier 87: Wide-field View in The Virgo Cluster | Schmidt Telescope

Galaxy Messier 87: Wide-field View in The Virgo Cluster Schmidt Telescope

Image of the Virgo cluster of galaxies taken with the Palomar Observatory 48-inch Schmidt Telescope as part of the Digitized Sky Survey 2 (DSS2). The giant elliptical galaxy Messier 87 is seen in the center, while Messier 84 and 86 are the two bright galaxies forming part of the small group on the center right of the image. New observations obtained with European Southern Observatory’s Very Large Telescope (VLT) have shown that the halo of stars around Messier 87 has been truncated, possibly because of interaction with Messier 84. The observations also reveal that Messier 87 and 86 are moving towards each other.

The Digitized Sky Survey (DSS) is a digitized version of several photographic astronomical surveys of the night sky, produced by the Space Telescope Science Institute between 1983 and 2006.

The Halo of Galaxy Messier 87 in Virgo | Burrell Schmidt Telescope

The Halo of Galaxy Messier 87 in Virgo | Burrell Schmidt Telescope


The huge halo around giant elliptical galaxy Messier 87 appears on this very deep image. An excess of light in the top-right part of this halo, and the motion of planetary nebulae in the galaxy, are the last remaining signs of a medium-sized galaxy that recently collided with Messier 87. The image also reveals many other galaxies forming the Virgo Cluster, of which Messier 87 is the largest member. In particular, the two galaxies at the top right of the frame are nicknamed "the Eyes".

Note: The black circles visible are coverage gaps where we lacked image data.

The Case Western Reserve University’s Burrell Schmidt Telescope wide-field telescope, owned and operated by Case Astronomy, is located at Kitt Peak National Observatory. It is used for deep wide-field imaging and surveys and was installed on Kitt Peak in 1979.

The Whale Galaxy: NGC 4631 in Canes Venatici | Hubble

The Whale Galaxy: NGC 4631 in Canes Venatici | Hubble


The NASA/European Space Agency Hubble Space Telescope has peered deep into NGC 4631, better known as the Whale Galaxy. Here, a profusion of starbirth lights up the galactic center, revealing bands of dark material between us and the starburst. The galaxy’s activity tapers off  in its outer regions where there are fewer stars and less dust, but these are still punctuated by pockets of star formation.

The Whale Galaxy is about 30 million light-years away from us in the constellation of Canes Venatici (The Hunting Dogs) and is a spiral galaxy much like the Milky Way. From our vantage point, however, we see the Whale Galaxy edge-on, seeing its glowing center through dusty spiral arms. The galaxy's central bulge and asymmetric tapering disc have suggested the shape of a whale or a herring to past observers.

Many supernovae—the explosions of hot, blue, short-lived stars at least eight times the mass of the Sun—have gone off in the core of the Whale Galaxy. The stellar pyrotechnics have bathed the galaxy in hot gas, visible to X-ray telescopes like the European Space Agency’s XMM–Newton. Comparing the optical and near-infrared observations from Hubble with other telescopes sensitive to different wavelengths of light helps astronomers gather the full story behind celestial phenomena.

From such work, the triggers of the starburst in the Whale Galaxy and others can be elucidated. The gravitational "feeding" on intergalactic material, as well as clumping caused by the gravitational interactions with its galactic neighbors, creates the areas of greater density where stars start to coalesce. Just as blue whales, the biggest creatures on Earth, can gorge themselves on comparatively tiny bits of plankton, so the Whale Galaxy has become filled with the gas and dust that powers a high rate of star formation.

Thackeray's Globules: Nebula IC 2944 in Centaurus | Victor Blanco Telescope

Thackeray's Globules: Nebula IC 2944 in Centaurus | Victor Blanco Telescope

This image was obtained with the wide-field view of the Mosaic II camera on the 4-meter Victor Blanco telescope at Cerro Tololo Interamerican Observatory. An array of dark Bok globules, known as Thackeray's Globules, can be seen in silhouette against the emission nebula IC 2944 in the constellation Centaurus. These dense, opaque dust clouds are silhouetted against nearby bright stars in the busy star-forming region. The image was generated with observations in the B (blue), I (orange) and Hydrogen-Alpha (yellow) filters. In this image, north is to the right, and east is up. This is one of the last observations completed with the Mosaic II camera before it was decommissioned.

Distance: ~6,500 light years

Astronomer A.D. Thackeray first spied the globules in IC 2944 in 1950. Globules like these have been known since Dutch-American astronomer Bart Bok first drew attention to such objects in 1947.

However, astronomers still know very little about their origin and nature, except that they are generally associated with areas of star formation, called 'HII regions' due to the presence of hydrogen gas. IC 2944 is filled with gas and dust that is illuminated and heated by a loose cluster of massive stars. These stars are much hotter and much more massive than our Sun.

These thick clouds of dust, known as the Thackeray globules, are silhouetted against the glowing gas of the nebula. These globules are under fierce bombardment from the ultraviolet radiation from nearby hot young stars. They are being eroded away and also fragmenting, rather like lumps of butter dropped onto a hot frying pan. It is likely that Thackeray’s globules will be destroyed before they can collapse and form new stars. 

The 4-meter Víctor M. Blanco Telescope was commissioned in 1974. It is a near twin of the Mayall 4-meter telescope on Kitt Peak. In 1995 it was dedicated and named in honor of Puerto Rican astronomer Víctor Manuel Blanco. It is also part of the Dark Energy Survey (DES), a visible and near-infrared survey that aims to probe the dynamics of the expansion of the Universe.

Earth: In the Grip of Global Heat | NASA’s Goddard Institute for Space Studies

Earth: In the Grip of Global Heat NASA’s Goddard Institute for Space Studies

This animation shows the daily maximum surface air temperature across Northern Africa, the Middle East, and South Asia from June 15 to June 25, 2024.

It is only the beginning of the summer season in the Northern Hemisphere, but Earth is already roasting. Scientists from NASA’s Goddard Institute for Space Studies (GISS) recently reported that May 2024, the hottest May in NASA’s global surface temperature analysis, marked a full year of record-high monthly temperatures. Likewise, the National Oceanic and Atmospheric Administration (NOAA) recently reported that January through May 2024 ranked warmest on its 175-year temperature record. On June 19, 2024, the Northern Hemisphere was running 1.1 degrees Celsius (1.9 degrees Fahrenheit) above normal, according to an analysis of meteorological data from Climate Reanalyzer.

In this context, early summer heatwaves in the Northern Hemisphere have been fierce. Just as Central America and the southwestern and eastern United States saw blasts of heat in May and June, temperatures also soared in the Middle East, South Asia, and Africa. The series of heat waves has contributed to large numbers of deaths, strained power grids, and challenged meteorological records.

This animation shows the daily maximum surface air temperature across Northern Africa, the Middle East, and South Asia from June 15 to June 25, 2024. It was produced by combining satellite observations with temperatures predicted by a version of the Goddard Earth Observing System (GEOS) global model. It uses mathematical equations to represent physical processes in the atmosphere. The darkest red areas indicate temperatures of more than 40°C (104°F).

According to news reports, nighttime temperatures were as high as 35.2°C (95.4°F) in Delhi on June 18, one of the hottest nights the city has seen in decades. In Greece, temperatures soared to 44.5°C (112.1°F) amid the closure of schools and historical sites. The Saudi National Center for Meteorology reported temperatures up to 49°C (120°F) in and around Mecca during Hajj.

In many cities, extreme temperatures collided with limited access to air conditioning, large outdoor events, high nighttime temperatures, a lack of green space, urban heat islands, and other factors to leave millions of people in hot and often humid conditions. The circumstances triggered not just discomfort but heat exhaustion and heatstroke in places. The annual Hajj pilgrimage to Mecca in Saudi Arabia proved particularly deadly in mid-June, but news reports indicate that the heat was associated with hospitalizations and deaths in India, Pakistan, Egypt, and Greece as well.

According to the World Health Organization (WHO), heat stress is the world’s leading cause of weather-related deaths and can exacerbate underlying illnesses including cardiovascular disease, diabetes, mental health conditions, and asthma. Researchers have calculated that roughly 489,000 heat-related deaths occur each year, with 45 percent of the deaths in Asia and 36 percent in Europe.

“For older adults with physical health problems, temperatures as low as 26.7°C (80°F) can pose significant danger. And when humidity is as high as 90 percent, even 25.6°C (78°F) can be hazardous,” said Deborah Carr, a Boston University sociologist who specializes in the study of aging. “Nighttime heat is especially harmful for older adults whose homes lack air conditioning or who can’t afford to run their air conditioners for long periods.”

Carr is part of a research team that used temperature and climate data archived by NASA and demographic data to identify parts of the world at the greatest risk of current and future heat exposure. They published their results with the Nature Communications journal in May 2024. They found that, in 2020, about 14 percent of the world’s population 69 years of age or older resided in areas where the average maximum temperature exceeded 37.5°C (99.5°F)—the level at which even brief exposure can be dangerous for older adults. The researchers projected that by 2050, more than 23 percent of that age group will face maximum temperatures that exceed 37.5°C—an increase of around 200 million older adults.

To prepare, Giacomo Falchetta, one of the authors of the study and a researcher at the Euro-Mediterranean Center on Climate Change, recommended a number of tailored public approaches. Well-resourced cities might increase investments in early warning systems and ride services to cooling centers and hospitals. By using remote sensing and geographic information systems, public officials could identify neighborhoods with high levels of heat exposure, and expand power grids to manage the increasing demand for air conditioning, he said. In contrast, improving access to high-quality housing, air conditioning, and clean water could have the greatest impact in cities with fewer resources, he added.

There are steps individuals can take to minimize risks as well. “The number one thing that older adults need to recognize is that they’re not the same person they were 50 years ago,” said Carr. “Biological changes mean that we can’t tolerate heat as well in our older years. Stay indoors during heat waves. If you have to go outside, get your activities done in the early morning or evening, when temperatures cool down. Drink plenty of water. Don’t use the oven, especially in small homes. Be sensitive to symptoms like dizziness and call for medical attention.”

Northern Lights over Shallow Lake, Ontario, Canada

Northern Lights over Shallow Lake, Ontario, Canada





On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth.

Earth auroras have different names depending on the pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

China's Chang'e-6 Retrieves over 1,935 Grams of Samples from Moon's Far Side

China's Chang'e-6 Retrieves over 1,935 Grams of Samples from Moon's Far Side

China's historic Chang'e-6 mission collected a total of 1,935.3 grams of samples from the far side of the Moon, the China National Space Administration (CNSA) announced on Friday, June 28, 2024, as the valuable samples were handed over to the Chinese Academy of Sciences at a special ceremony held in Beijing.

China's historic Chang'e-6 probe has retrieved a total 1,935.3 grams of samples from the far side of the Moon, the China National Space Administration announced on Friday, as the valuable samples were handed over to the Chinese Academy of Sciences at a special ceremony held in Beijing.

The Chang'e-6 probe's returner touched down in north China's Inner Mongolia Autonomous Region on Tuesday, June 25, completing its momentous 53-day mission to the lunar far side and marking another milestone in China's space exploration program.

The international space science community has also hailed the historical significance of the accomplishment, and believe the samples can offer global scientists the chance to uncover hidden secrets from the Moon's mysterious far side.

After the samples were brought back to Beijing earlier this week and officially handed over to scientists, the Chang'e-6 mission has now transitioned from the engineering implementation stage to a new phase of scientific research. Following the safe transportation of the precious samples to the lunar sample lab, researchers will carry out storage and processing tasks as planned and later initiate scientific research work.

An initial visual inspection of the contents of the sealed container has already provided interesting indications that the mineral and chemical composition may differ significantly compared to the samples brought back by the predecessor Chang'e-5 probe. It retrieved a total of 1,700 grams from the surface of the near side of the moon in December 2020.

"From the appearance, we found that the Chang'e-6 samples look stickier than previous [lunar] samples and are more compacted, which is clear to see. Certainly, we also look forward to new scientific discoveries and results through systematic follow-up work," said Ge Ping, a spokesman for the Chang'e-6 mission.

The scientific research regarding these samples will involve multiple academic disciplines and research directions, including conducting basic physical and chemical properties analysis, as well as in-depth geological and geochemical studies, with scientists expected to have the opportunity to delve into the secrets contained within these precious samples in the coming months.

"As for the next step, the National Astronomical Observatories of Chinese Academy of Sciences, which is the general unit of the ground system of our lunar mission, will first unseal the sample container, and then prepare the samples obtained from drilling and surface retrieval, and pack them for storage. At the same time, according to the regulations on lunar sample management issued by the China National Space Administration, it is expected that applications will be open to domestic scientific research institutions and scientists after half a year," said Ge.

The Chang'e-6 probe, comprising an orbiter, a lander, an ascender and a returner, was launched on May 3, 2024, from south China's tropical island province of Hainan.

Supported by the Queqiao-2 relay satellite—put into position shortly before the mission to aid communication with the 'dark side' of the Moon—the lander-ascender combination landed at the designated lunar landing area in the South Pole-Aitken (SPA) Basin on June 2 and began its pivotal sampling work.

The colossal SPA Basin was formed by a celestial impact over 4.3 billion years ago and has a diameter of 2,500 km and a depth of about 13 km. It is believed to be the largest impact crater found in the inner solar system so far.

Experts believe the study of the samples will increase understandings of the formation of Earth, the Moon, and the solar system, and could advance efforts to learn how to use resources on the moon for future space exploration.

China had already been the first country to achieve a successful soft landing on the Moon's far side with its Chang'e-4 mission back in 2019.

Earlier this month, an expert involved in planning the fourth phase of China's lunar exploration projects, said the future Chang'e-7 and 8 missions will help pave the way for the development of deep space exploration technologies, and enable China to push ahead with its plan for establishing a scientific research station on the Moon to carry out long-term research.

Pan of Spiral Galaxy NGC 3254: A Galactic Powerhouse | Hubble

Pan of Spiral Galaxy NGC 3254: A Galactic Powerhouse | Hubble

This image shows the spiral galaxy NGC 3254, observed using Hubble's Wide Field Camera 3 (WFC3). WFC3 has the capacity to observe ultraviolet, visible and near-infrared light, and this image is a composite of observations taken in the visible and infrared. In this image, NGC 3254 looks like a typical spiral galaxy, viewed side-on. However, NGC 3254 has a fascinating secret that it is hiding in plain sight—it is a Seyfert galaxy, meaning that it has an extraordinarily active core, known as an active galactic nucleus, which releases as much energy as the rest of the galaxy put together. 


Distance: 118 million light years

Seyfert galaxies are not rare—about 10% of all galaxies are thought to be Seyfert galaxies. They belong to the class of “active galaxies”—galaxies that have supermassive black holes at their centers that are actively accreting material. They release vast amounts of radiation as it is accreted. There is a second, far more active, type of active galaxy that is known as a quasar. The active cores of Seyfert galaxies, such as NGC 3254, are brightest when observed in light outside the visible spectrum. At other wavelengths, this image would look very different, with the galaxy’s core shining extremely brightly.

A Golden Atmospheric Glow Crowns Earth's Horizon | International Space Station

A Golden Atmospheric Glow Crowns Earth's Horizon | International Space Station

A long exposure shot taken aboard the International Space Station shows a golden atmospheric glow crowning Earth's horizon as the orbiting laboratory soared 267 miles over the South Pacific Ocean.

The orange hue enveloping Earth is known as airglow—diffuse bands of light that stretch 50 to 400 miles into our atmosphere. The phenomenon typically occurs when molecules (mostly nitrogen and oxygen) are energized by ultraviolet (UV) radiation from sunlight. To release that energy, atoms in the lower atmosphere bump into each other and lose energy in the collision. The result is colorful airglow.

Airglow reveals the workings of the upper reaches of our atmosphere. It can help scientists learn about the movement of particles near the interface of Earth and space, including the connections between space weather and Earth weather. Satellites offer one way to study this dynamic zone. NASA’s Ionospheric Connection Explorer (ICON) satellite, launched in 2019, is helping scientists understand the physical processes at work where Earth’s atmosphere interacts with near-Earth space.

A Tour of The Serpens Nebula | James Webb Space Telescope

A Tour of The Serpens Nebula | James Webb Space Telescope

 

This video tours the Serpens Nebula, a star-forming region that lies 1,300 light-years away from Earth.

A new image of Serpens from NASA’s James Webb Space Telescope shows an intriguing group of aligned protostellar outflows within one region of the nebula. Protostellar outflows are formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds.

This region is also home to several captivating features—the flapping shadow of a planet-forming disk, nicknamed the “Bat Shadow,” areas of varying density that appear as crevices, and a special binary protostar.
